Signal Adapter SA-1 enables to adjust the signal level in the amp effects loop to the signal level required by effects.
SA-1 let you avoid distortions caused by too high signal level or reduce hums caused by too low signal level.
Signal adjustment is done by two separated modules: ATTENUATION and BOOST.
When the signal which goes to the effect is to high SA-1 attenuates it and boosts the return signal.
When the signal which goes to the effect is to low SA-1 boosts it and attenuates the return signal.
On the front panel of SA-1 there are attenuation and boost regulators for matching the signal of both sections.
Adapter can be installed in the rack 19” using the GLAB 1U RMS FRONT PANEL.
